Analysis method used for in-mold decoration injection molding

Abstract

The invention relates to an engineering analysis method used for in-mold decoration injection molding. The method is divided to molding engineering analysis, grid interface processing and injection engineering analysis, and comprises the following steps: first, establishing a film grid, a molding mould grid and an injection molding grid, importing the film grid and the molding mould grid, and setting a molding parameter for engineering analysis so as to obtain molding analysis information; operating according to the injection molding grid and the molding analysis information to obtain an embedded film grid and an injection resin grid; and importing the embedded film grid and the injection resin grid, and setting an injection parameter for mold flow analysis so as to obtain in-mold decoration analysis information. The engineering analysis method is integrated with a molding analysis program and an injection analysis program, improves the analysis precision of the in-mold decoration injection molding, and shortens the engineering analysis time of the in-mold decoration injection molding, thereby shortening development time of a product and reducing cost.

Description

Technical field: [0001] The invention relates to an analysis method, in particular to an engineering analysis method for in-mold decoration injection molding. Background technique: [0002] At present, the plastic injection molding process is the most important discipline in the contemporary polymer processing procedures. Because the process has the advantages of easy molding of plastic parts, mass production, low production cost and suitable for complex molding, it is widely used in consumer goods and information appliances. , electronic communications and automobile and motorcycle components, has become the most widely used technology in polymer processing procedures. [0003] For Taiwan, China, the mold industry ranks fourth in the world, among which plastic injection molds are the most important. With the improvement of new materials, production technology and equipment, and even new products are changing with each passing day, and they are listed on the market at an ext...

Problems solved by technology

[0010] One of the main difficulties in the simulation of the injection molding process is the instantaneous free surface of the molten resin. When the in-mold decoration injection molding integrates processing technologies such as flat printing, thermocompression molding, precision punching and injection molding, the moldable film must be overcome during the injection process. Problems such as positioning, ink scouring, stretching and warping, etc., the application of computer-aided engineering analysis technology can help to understand the cause of the problem, but there are still too many unreasonable applications of commercial computer-aided engineering technology in the injection molding process of in-mold decoration Assumptions
